What is the difference between a heterozygous and a homozygous allele use an example to explain?

Homozygous means that both copies of a gene or locus match while heterozygous means that the copies do not match. Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

What is heterozygous and homozygous examples?

Homozygous means that the organism has two copies of the same allele for a gene. … Heterozygous means that an organism has two different alleles of a gene. For example, pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white).

What is the difference between a heterozygous and a homozygous allele quizlet?

What is the difference between homozygous and heterozygous? Homozygous is having two identical alleles for a particular gene. Heterozygous is having two different alleles for a particular gene.

Is it better to be homozygous or heterozygous?

So in the homozygous condition, a cell possesses either two same type dominant alleles (RR) or recessive alleles (rr). Whereas in the heterozygous condition the cell contains two non-identical alleles (Rr).



Summary.

Homozygous Heterozygous
When two identical alleles are present. When two different alleles are present.

What’s an example of heterozygous?

For every gene, you inherit two alleles: one from your biological father and one from your biological mother. … If the two versions are different, you have a heterozygous genotype for that gene. For example, being heterozygous for hair color could mean you have one allele for red hair and one allele for brown hair.

Is AA homozygous or heterozygous?

Two dominant alleles (AA) or two recessive alleles (aa) are homozygous. One dominant allele and one recessive allele (Aa) is heterozygous.

Is SS heterozygous or homozygous?

Specifically, heterozygous (Ss) individuals express both normal and sickle hemoglobin, so they have a mixture of normal and sickle red blood cells. In most situations, individuals who are heterozygous for sickle-cell anemia are phenotypically normal. Under these circumstances, sickle-cell disease is a recessive trait.
